How did you OC? Did you just change the multiplier or fiddle with other settings? Typically the idle speed would be much lower.
I didnt do anything after i installed the new processor it was doing that on its own, a friend of mine is having the same issue.
That's TurboBoost in action. With current Intel CPUs, the base clock is rarely the clockspeed you actually get, with that base speed only being used if you are close to thermal throttling or have a board with weak VRMs restricting the amount of power a CPU can draw. So long as you have thermal and power headroom, you will get clockspeeds higher than the base clock, and 3.8-3.9GHz on all cores is pretty common for the i5 8400/8500.
